How to Have Two Withholding Tax Code in One invoice

Question

Hello,
We are using Extended Withholding Tax, and we have defined 9 Withholding Tax type specials, this because is the same withholding type, but we different %, also we have defined more than one Withholding Tax Code, for each one. This kind of Withholding Tax in Venezuela it is called ISAE, and for one invoice I could have more than one ISAE Withholding Tax, in this with have configurated diferents withholdings tax types, but it is a issue because, the system generate one Certificate Numbering for Withholding Tax, but for us this needs to be the same,and only generates one Certificate Number and make the sum of the two amounts. Because is the same Withholding Tax, we need to report only one.
E.g. I post an invoice 1000999, with two Withholding Tax type, 23 -with tax code 01 and 24 with tax code 02, when i Generate the report I get:
Vendor Certificate Number Wh. t.t. Wtx Amount in RC wt amount
10000 00000000001 23 01 90000 2000
10000 00000000002 24 02 90000 1500
We need:
Vendor Certificate Number Wh. t.t. Wtx Amount in RC wt amount
10000 00000000001 23 01 90000 3500
We tried to defined only one Withholding Tax type with all the Withholding Tax Code, but the system doesn't allow to post in the vendor master data, more that one Withholding Tax type, we tried to leave it blank, but when we do the FB60, we can´t select multiple Tax Code.
How we can post a document with more  tham one tax code? or what we have to do to solve the problem?
I appreciate all the help you can provide me.

Hello Mauri
Thanks for your answer, but in this moment we have the configuration exactly like you suggest, but in the moment of we generate the certification number we get two or more numbers, and we only need that the systme generates only one. It is correct that the sistem generates two or more because in one invoice we need and we use two or more wt type ISAE, but for Legal Reasons we need that the system generates only one certificated number, because is the same wt type.  You know if we can do any validation? or we must do anything else to get only one certificated number? we never know or is not a rule to use a specific combination of Wt Type.
